'1 Claims.

This invention relates to a device for cleaning a window inside and outside at one and the same time.

Another object of the invention is to provide a pair of telescopic channel members having means for adjustably connecting the same.

A further object of the invention is to provide an inverted U-shap-ed split tube in which flexible vertically moving members carry a series of brushes or mops for cleaning windows on both sides at one and the same time.

A still further object of the invention is to provide means for carrying vertically movable brushes adapted to contact both sides of a window glass together with means for horizontal movement of the carrying means.

Other features and advantages will become more readily apparent from the following description and the accompanying illustrative drawings in which:

Figure 1 is an elevational view of my device shown in position upon a window,

Figure 2 is a detail perspective view of a channel member,

Figure 3 is an enlarged vertical sectional view of a window showing my device attached thereto,

Figure 4 is a front elevation of the device,

Figure 5 is a top plan view of my device,

Figure 6 is a section on line 66 of Figure 3, and

Figure 7 is a detail view of a flexible tubing.

The same elements of my invention are indicated by the same reference characters in both the drawings and in the following specification and in which Ill, represents my window cleaner as an entirety, the details of construction being as follows: On the inside of the window II, is a pair of telescopically connected channe1 members I3 and I4, the upper member I3, of which is provided with a right angular extension I5, and outside of the window is located a similar pair of telescopically connected channel members I6 "and I1, the upper one I6, of which is provided with a right angular extension I8, telescopically seated Within the extension I5, and connected thereto at each side by means of a bolt I9, operating through a slot 26, in the member I5, a wing nut being provided on the bolt whereby the said members I8 and I5, may be secured in adjustable position. Mounted on the top of the member I5, are rollers 2| and 22, adapted to bear against the window frame member 23, and under the said member I5, are a pair of similarly disposed rollers 24, adapted to seat upon the window stile 25.

Operating within the inner and outer channel members I3 and I4, I6 and I1, and through the right angular extensions I5 and I8, is a flexible tube 26, having fixed thereto at suitably spaced intervals plates 21, projecting through the longitudinal slots 28, of said channel members and adjustably attached to the plates 21, are similar plates 28, secured to the brushes 29, said brushes bearing upon the inside and outside svrfaces of the window glass 30 and 3|. The member 2 6, when passing through the horizontal portions I5 and I8, of the channel members, o'erates upon and beneath rollers 32 and 33, respectively.

Slidably operating upon the inner channel member I3, is a collar 34, to which is attached a handle 35. Said collar encircles the member I3, and is provided with inturned tongues on its inner side which operate within the longitudinal slots 28, and engage the flanges 36 and 31, of the member I3, which collar is also provided with band extensions 38 and 39 which are secured to the said member 26, whereby when the handle 25, is moved up and down upon the member I3, the flexible member 26, is likewise moved up and down, carrying with it the inner brushes 29' and the outer brushes 29.

The lower ends of the members I4 and I1, are connected by bars 40 and 41, having rollers 42 and 43 on their outer ends, to the longitudinal tracks 44 and 45, whereby the said members I4 and I1 are held in rigid vertical position and also whereby the device may be operated horizontal- 1y back and forth throughout the width of the said window II. Connected to the trackway 44, is an L-shaped channel member 46, having an up turned outer arm 41. This channel member is adapted to receive the lower stile 48 of the lower sash 49, of said window I I, whereby the said member 46, will be held seated longitudinally under said sash and whereby the flange 50, projecting downwardly from the member 45, will be held secured against the said outer surface of said stile 48. The member 46, is also formed of a pair of telescopically connected members whereby the same may be adjusted to windows of varying widths.

As it may be occasionally required to use my device with a single sash window the sections I4 and I1, of the said telescopic members may be removed and the upper sections I3 and I6, only be used. In this case the tubing 26, will hang free below the members I3 and I6, and through its flexibility will move out of vertical alignment with said members l3 and I6, to permit the upper brushes 29 and 29, to move freely from top to bottom of the glass 30.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in shape, size and rearrangement of details and parts such as come w thin the purview of the invention claimed may be resorted to, in actual practice, if desired.

Having described my invention, that wh ch I claim to be new and desire to procure by Letters Patent is:

1. A window cleaning device including spaced parallel vertical channel members. including facing longitudinal openings and comprising telescopically connected channel members to vary the length thereof, angular extensions at the up er ends of said channel members telescopically connected and havin means to movably support the same on a top stile of a window sash for horizontal movement across the pane thereof, a flexible tube movable endwise in said channel members, window cleaning members operatively connected to said tube and movable therewith in the opening of the channel members, and means on the channel members and connected to the tube through the opening thereof to move said tube.

2. A window cleaning device incl ding spaced parallel vertical channel members, including faciing longitudinal openings and comprising telescopically connected channel members to vary the length thereof. angular extensions at the unper ends of said channel members telescopically connected and having means to movably support the same on a top stile of a window sash for horizontal movement across the pane thereof, a flexible tube movable endwise in said channel members, window cleaning members operatively connected to said tube and movable therewith in the opening of the channel members, means on the channel members and connected to the tube through the opening thereof to move said tube, and means to movably support the channel members at the top of a window sash for movement horizontally across the win dow pane thereof.
